Description

Technical Field

[0001] The present application relates to the technical field of inverters, and in particular to a wall-mounted inverter, and further to an energy storage system including the wall-mounted inverter. Background Art

[0002] Inverters typically convert DC power into AC power through an inverter circuit by controlling the on and off switching of switching tubes. When discharging the energy storage system, the inverter converts the stored DC power into AC power for output; when charging, it converts the input AC power into the DC power required by the energy storage system for charging. Inverters can perform charging and discharging operations, providing support for bidirectional energy conversion. Energy storage inverters are widely used in renewable energy power generation systems such as solar and wind power, as well as in power storage systems, microgrid systems, and electric vehicle charging stations. They provide key support for the energy conversion between DC energy and AC loads, promoting the application of clean energy and energy transformation.

[0003] During the installation of the inverter, when the connector used is a non-quick-plug terminal, it is necessary to reserve an openable and closable wiring window on the inverter. The wiring work is achieved by opening the wiring window and connecting the external wiring harness to the inside of the inverter. For wall-mounted inverters, if the wiring window is set on the front of the inverter, it will affect the appearance of the product and reduce the aesthetics of the product. If it is placed on the back of the inverter, interference will occur between the wiring window and the wall, making it inconvenient to open and install the external wiring harness. For this reason, a wall-mounted inverter is proposed in this application. Utility Model Content

DETAILED DESCRIPTION

[0042] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0043] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0044] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0045] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0046] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0047] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0048] In existing inverters, since some inverters have the wiring port set at the bottom, when using quick-plug terminals, the external wiring harness can be connected to the inverter directly from the bottom of the inverter. Even if the inverter is hung on the wall, it can be accessed and wiring operations can be performed. For wall-mounted inverters, the user only needs to adjust his body posture.

[0049] However, some inverters use non-quick-plug terminals. In this case, it is necessary to reserve an openable and closable wiring window on the inverter. When wiring is required, the wiring window is first opened and then the external wiring harness is connected to the inner wall of the inverter, and then the wiring window is closed. Since the wiring window is set on the outer surface of the inverter, if it is placed on the front of the inverter, the overall aesthetics of the product will be reduced. If the wiring window is set on the side close to the wall, it is not convenient for workers to access and open it, which affects the wiring process. To address the above problems, a wall-mounted inverter is proposed in the present application.

[0050] Figure 1 It is a three-dimensional schematic diagram of a wall-mounted inverter according to an embodiment of the present application, and includes: a wall-mounted plate 1 configured to be installed on a wall surface, an inverter body 2 rotatably mounted on the wall-mounted plate 1 and configured so that the rotation center axis extends in a vertical direction, and a wiring unit 3 openably arranged on the inverter body 2 near the side of the wall-mounted plate 1, the wiring unit 3 being configured to rotate with the inverter body 2 to be exposed for user contact; along a direction perpendicular to the rotation center axis, one end of the inverter body 2 is rotatably connected to the wall-mounted plate 1 through a transfer unit 4, and the other end is fixed to the wall-mounted plate 1 through a locking unit 5.

[0051] In this arrangement, reference Figures 1-6 The wall-mounted inverter described herein is conveniently mounted on the wall surface of the inverter by providing a wall-mounted plate 1, thereby providing a foundation for the installation of the inverter; the inverter body 2 is rotatably mounted on the wall-mounted body by means of an adapter unit 4; and the wiring unit 3 provided on the side of the inverter body 2 close to the wall-mounted plate 1 can be opened and closed to facilitate the connection of an external wiring harness to the interior of the inverter; since the rotation center axis of the inverter body 2 extends in the vertical direction, it is convenient to drive the inverter to rotate around the vertical direction, exposing the wiring unit 3 close to the wall-mounted plate 1 for the user to access and connect the wiring; thereby, while ensuring the aesthetics of the wiring unit 3 when installed against the wall, there is no interference between the wiring unit 3 and the wall-mounted plate 1, making it convenient for the user to access and open the wiring unit 3 at any time for wiring. After completion, the inverter body 2 is rotated and reset by means of the adapter unit 4 under the action of an external force, and the inverter body 2 is fixed to the wall-mounted plate 1 by the locking unit 5, which can meet the user's usage needs.

[0052] In one case of this embodiment, reference Figure 9 、 Figure 10 and Figure 11During actual installation, first fix the wall-mounted plate 1 on the wall-mounted plane, then rotate the inverter body 2 and install it on the wall-mounted plate 1 through the adapter unit 4, and finally rotate the inverter body 2 until its wiring unit 3 is close to or in contact with the wall-mounted plate 1, and finally fix the other end of the inverter body 2 to the wall-mounted plate 1 through the locking unit 5, thereby completing the installation and fixation of the inverter.

[0053] In another case of this embodiment, reference Figure 9 、 Figure 10 and Figure 11 When it is necessary to disassemble or assemble the external wiring harness, first open the locking unit 5 to separate the other end of the inverter body 2 from the wall-mounted plate 1, and then use external force to drive the inverter body 2 to rotate relative to the wall-mounted plate 1 through the adapter unit 4, thereby driving the wiring unit 3 away from the wall-mounted plate 1 or keeping a distance from it. Then, manually open the wiring unit 3 to assemble or disassemble the external wiring harness. After completion, rotate the inverter body 2 in the opposite direction to achieve reset.

[0054] The wall-mounted inverter proposed in this embodiment adopts a wall-mounted plate 1, a transfer unit 4 and a locking unit 5, and has a simple overall structure. While ensuring the normal wall-mounting function of the inverter, the wall-mounted plate 1 is used to shield the wiring unit 3, ensuring its beautiful outer surface. At the same time, it also effectively avoids the interference between the wiring window 31 of the traditional wall-mounted inverter and the wall surface, which makes wiring inconvenient, and has strong practicality.

[0055] The following will introduce further specific implementation or refinement and improvement process of the wall-mounted inverter through exemplary descriptions, so as to further improve it or for improvement considerations in other aspects.

[0056] In actual operation of this embodiment, reference Figure 4 、 Figure 5 and Figure 6 , along the direction perpendicular to the central axis of rotation, a first side panel 21 and a second side panel 22 are formed at both ends of the inverter body 2, and a third side panel 11 is formed at one end of the wall-mounted panel body 1 close to the first side panel 21. The third side panel 11 is pressed next to the first side panel 21 and the two are locked by the locking unit 5.

[0057] It can be known that by setting a first side panel 21 and a second side panel 22 at both ends of the inverter body 2, the wall-mounted panel body 1 is provided with a third side panel 11 for crimping onto the first side panel 21, thereby realizing an effective connection between the wall-mounted panel body 1 and the inverter body 2, and providing an installation basis for the locking unit 5, so as to facilitate the detachable connection between the two through the locking unit 5.

[0058] Illustratively, the third side panel 11 is pressed onto the outside of the first side panel 21 and the two are locked by the locking unit 5. By pressing the third side panel 11 onto the outside of the first side panel 21, it is convenient to lock the two by the locking unit 5. Of course, the third side panel 11 can also be pressed onto the inside of the first side panel 21. Its specific structure is not a restrictive provision of this embodiment.

[0059] In one case of this embodiment, the locking unit 5 includes: a clamping member 51 arranged on one of the first side panel 21 and the third side panel 11, and a clamping slot 52 opened on the other of the first side panel 21 and the third side panel 11; when the clamping member 51 is engaged with the clamping slot 52, the first side panel 21 and the third side panel 11 are locked and fixed.

[0060] It is not difficult to see that the use of the card slot 52 and the card connector 51 to facilitate the rapid disassembly and assembly between the first side panel 21 and the third side panel 11. While ensuring the connection strength between the first side panel 21 and the third side panel 11, the two are quickly fixed, and the installation and disassembly process is more convenient and quick.

[0061] On this basis, the clamping slot 52 is opened at the front end of the third side plate 11 facing the first side plate 21 , and part of the bottom surface is configured as a guiding inclined surface for assisting the clamping member 51 to penetrate.

[0062] It can be seen that since the slot 52 is opened at the front end of the third side panel 11, when the inverter body 2 is rotated to a suitable position, the clamping member 51 can be clamped into the inside of the slot 52, thereby achieving the fixation of the first side panel 21 and the third side panel 11; and the guide slope can assist the clamping member 51 to smoothly enter the inside of the slot 52 and reach the preset position to complete the clamping action.

[0063] Exemplarily, the above-mentioned clamping member 51 can be set as a cylindrical pin shaft, and the end of the clamping groove 52 away from the guide slope can be set as a circular notch, and the outer diameter of the cylinder is slightly larger than the inner diameter of the circular notch, so that the cylindrical pin shaft is interference-fitted inside the circular notch, thereby achieving a clamping fixation between the two.

[0064] Of course, not limited to this, the above-mentioned clamping member 51 can also be set to other shapes, for example, triangular prism, quadrangular prism, pentagonal prism, hexagonal prism, etc., and the shape of the card slot 52 can also be set at will, for example, triangular, quadrilateral, pentagonal, hexagonal, etc., which is not specifically limited in this embodiment.

[0065] Exemplarily, the above-mentioned clamping parts 51 can be arranged in sequence along the first side panel 21 of the inverter body 2, and correspondingly, the above-mentioned card slots 52 can be arranged along the third side panel 11. The specific numbers of the two can be selected as needed, and this embodiment does not make specific limitations here.

[0066] In another case of this embodiment, reference Figure 8 The locking unit 5 includes: a light hole opened in one of the first side plate 21 and the third side plate 11, a threaded hole opened in the other of the first side plate 21 and the third side plate 11, and a bolt sequentially connected to the light hole and the threaded hole.

[0067] It can be known that the above-mentioned locking unit 5 can also adopt threaded holes, smooth holes and bolts to achieve a detachable connection between the first side panel 21 and the third side panel 11. While ensuring the effective fixation of the two, it also further increases the stability between the inverter body 2 and the wall-mounted plate body 1, and even if it is subjected to external force when wall-mounted, it will not have a significant impact.

[0068] In actual operation of this embodiment, reference Figure 4 、 Figure 5 and Figure 6 The adapter unit 4 includes: a supporting portion 41 arranged at one end of the wall-mounted panel body 1 away from the third side panel 11 and having an axial hole 411 therein, and a rotating shaft 42 arranged on the second side panel 22 and configured to rotate and pass through the inside of the axial hole 411.

[0069] It can be seen that by setting a supporting part 41 at the other end of the wall-mounted plate body 1, it is convenient to use the rotating shaft 42 fixed on the second side plate 22 to realize the rotational connection between the inverter body 2 and the wall-mounted plate body 1. The structure is simple and easy to operate, and it has strong practicality.

[0070] On this basis, a plurality of the rotating shafts 42 are sequentially arranged along the vertical direction, and the supporting parts 41 are arranged below the rotating shafts 42 and are arranged one-to-one correspondingly thereto.

[0071] It is not difficult to see that by providing a plurality of rotating shafts 42 and supporting parts 41 in sequence along the height direction, the connection reliability between the inverter body 2 and the wall-mounted plate body 1 is further enhanced.

[0072] For example, there are two of the above-mentioned rotating shafts 42 and supporting parts 41 along the vertical direction. Of course, the above-mentioned adapter unit 4 can also be a rotating hinge connected between the wall-mounted plate 1 and the inverter body 2. Its specific structure and form can be selected as needed, and this embodiment does not make specific limitations here.

[0073] In one case of this embodiment, reference Figure 1 and Figure 7 The wiring unit 3 includes: a wiring window 31 opened on the side of the inverter body 2 close to the wall-mounted plate 1, and a sealing cover 32 detachably installed on the outer periphery of the wiring window 31. When the inverter body 2 is locked with the wall-mounted plate 1, the sealing cover 32 and the two opposite side walls of the wall-mounted plate 1 are distributed in parallel.

[0074] It can be seen that by setting the wiring window 31 and the sealing cover 32, the connection and fixation of the external wiring harness are facilitated, and when the inverter body 2 and the wall-mounted plate body 1 are locked, the parallel distribution of the sealing cover body 32 and the two side walls of the wall-mounted plate body 1 also effectively ensures a smooth connection between the two.

[0075] It should be noted that a snap-fit ​​portion is provided on the periphery of the wiring window 31, and the sealing cover body 32 can be snap-fitted to the periphery of the above-mentioned snap-fit ​​portion, thereby realizing a detachable connection between the two; of course, a bolt connection method can also be used between the sealing cover body 32 and the wiring window 31, which is not specifically limited in this embodiment.

[0076] In actual operation of this embodiment, reference Figure 7 The wall-mounted plate body 1 is provided with a mounting hole 13 along the thickness direction, and the wall-mounted plate body 1 is fixedly mounted on the wall-mounted surface by a locking member 12 passing through the mounting hole 13 .

[0077] In this arrangement, the locking member 12 can be inserted into the mounting hole 13 to mount the wall-mounted plate 1 on a wall-mounted surface, such as a wall or the inner or outer wall of a box, thereby achieving a detachable connection of the inverter body 2.

[0078] For example, the mounting hole 13 can be a threaded hole, and the locking member 12 can be a locking bolt or an expansion screw; of course, other fixing methods can also be used, including but not limited to welding, bonding, bolt connection or plug-in matching to achieve relative fixation between the wall-mounted panel 1 and the wall-mounted surface. This embodiment does not make specific limitations here.

[0079] This embodiment also provides an energy storage system, including the wall-mounted inverter described above.

[0080] It can be seen that the above-mentioned wall-mounted inverter is installed on the energy storage system, the wall-mounted plate 1 is installed on the wall surface through the locking piece 12, and the inverter body 2 is rotatably installed on the wall-mounted body; and the wiring unit 3 provided on the side of the inverter body 2 close to the wall-mounted plate 1 can be opened and closed to facilitate the connection of the external wiring harness to the inside of the inverter; since the rotation center axis of the inverter body 2 extends along the vertical direction, it is convenient to drive the inverter to rotate around the vertical direction, exposing the wiring unit 3 close to the side of the wall-mounted plate 1 for the user to contact and connect the wiring; thereby ensuring the aesthetics of the wiring unit 3 installed against the wall, there is no interference between it and the wall-mounted plate 1, which makes it convenient for the user to contact and open the wiring unit 3 at any time for wiring. After completion, the adapter unit 4 is used to rotate and reset the inverter body 2 under the action of external force, and the inverter body 2 is fixed to the wall-mounted plate 1 by the locking unit 5, which can meet the user's usage needs.

[0081] The above examples primarily illustrate the wall-mounted inverter and energy storage system comprising the wall-mounted inverter of the present application. Although only some of the embodiments of the present application have been described, those skilled in the art will appreciate that the present application may be implemented in many other forms without departing from its subject matter and scope. Therefore, the examples and embodiments presented are to be considered illustrative rather than restrictive, and the present application may encompass various modifications and substitutions without departing from the spirit and scope of the technical solutions of the present application.
